The thermal diffusivities of a range of grey cast irons have been measured over the temperature range 200°–700°C using the flash method. Detailed metallographic examinations of the specimens have also been carried out. The effects of size, shape, and distribution of free graphite and of different matrix structures have been investigated. It has been found that the diffusivity of cast irons is strongly influenced by the graphite phase and, to a lesser extent, by the matrix structure.
